small donation problem =/

it's me snoopy i really have been getting annoyed by this visa giftcard i have and wanted to get rid of it becuz it has like 2 bucks on it so i decided to donate it to this server since it is my first server (my compter used to not let me play online until like march, thats also when i joined the server), but 1 problem im 13 and do not understand how to donate.

soooo how i thought i could fix the problem is by just sending all the card info to sos or satan if he knows soses paypal account but that may not work so please give me feedback on how to fix this freaking dumb problem. also later i might be able to donate more XD
